| Abstract | A dual Z-scheme fe(2)O(3)@MnO2 core/shell nanocube supported C3N4 ternary composite is rationally designed and successfully fabricated as a photocatalyst for water splitting. The as-prepared Fe2O3@MnO2/C3N4 ternary composite exhibits an enhanced visible light-induced absorbance capacity and superior photocatalytic activity for direct water splitting than that of pure g-C3N4. The photocatalytic efficiency is investigated by varying amounts of Fe2O3@MnO2/shell nanocubes in the ternary composite (10%wt, 20%wt and 30%wt). When the mass fraction of Fe2O3@MnO2 is determined to be 20%, the hydrogen evolution rate would achieve the maximum with a value of 124 mu mol*h(-1). The improved photocatalytic performance of Fe2O3@MnO2 ternary composite can be mainly attributed to improved visible light absorption range and construction of an effective dual Z-scheme interfacial heterojunction with a rapid separation and transfer of electron-hole pairs. |
